FlyPT 6DOF/Stewart/Hexapod Interface for linear and rotating actuators

For some strange reason in my case the legs doesn’t turn red while out of reach occurs.

If you have stay in last possible pose checked, the rig stays in the last possible position, so legs don't turn red.
But you see the thin lines still moving and you still receive the message of out of pose.
If you see the bit range output, the values are fixed, they don't change (there's a bug there, that makes info show with an error, but that's just the ! signal) because the rig stays in the last possible position.
I can't see that option in the image, but I think that's what you have.

Only to mention that I don’t see the small lignes moving but that’s also fine.

Could you also please add a network output option @pmvcda like Simtools has? Not everyone uses direct output to a microcontroller.

You should see this (increased size):

They are really thin. I can increase them and show in red when out of range.

Will take a look, but not for now.
Need to rework some parts of the code because of auto calibration. It will bring benefits in other areas for some new features, like scripting movements.

Right now I'm trying to put DCS in direct feed...
But can't even make it work on SimTools.
Seems like DCS ignores the lua script.... might be something stupid I'm making... not much experience with DCS

Maybe once you rework things you can include it then . It shouldn't take much effort and will allow greater compatibility.

I'd offer help with DCS but they've reworked the Lua script since I had it working natively so I think I would have to start from the beginning again. I can take a look though.

I'm looking at the new script right now... some minutes and I might get it working.

I know in the past you had to activate Lua scripting before using it.

This may no longer be valid though.

-- Please, set EnableExportScript = true in the Config/Export/Config.lua file
-- to activate this script!

Got the script working to a text file.
No need to edit the config.

Yes you are right, it needs more positive pitch to feel continous acceleration. Now I try to find the best motion feeling to use simtools tuning washout, etc. and the FlyPT filters... sometimes I can not find myself in the forest . But I have to say it's a very interesting and enjoyable entertainment . Its very hard to tweak alone by myself Very hard to recognise the real motion when I drive a car in VR. I feel something is wrong but can not know what it is. Im thinking to put a monitor on the rig, at least until I set all motions correctly.
About crank lenght, I'm affraid if I increase that, it would have much noticable backlash.

I don’t think you’re using the accelerations over 1G so logically, I don’t understand why the backlash could play a role there.

For the washout you could wait couple of days as the simtools filtering will be reworked in the upcoming release

I think the rig becomes jerky because of backlash. Sometimes when pitch moves forward very slowly it gets jerky and feels weird during descend with an airplane. I think it happens because of backlash. However my wormgear drives have very small backlash approximately 1-2mm.

Maybe for worm 1-2mm it’s “little” for planetary it would be huge.

With pitch, it can happened with the arms which are going up and they don’t have any weight on them, however the acceleration has to be pretty important.

You say it occurs with slow movement, I don’t see any reason for jerking there.

Try to smooth this signal more or check your accelerations or pid of your motor

It depends on the lever length and where measured so its relative.

Worms tend to have more friction so its possible that could cause some jerking at slow speeds.

In any case this thread is not appropriate for tuning individual rigs imo just because it uses the FlyPT interface.

OK, I have DCS working.
(Only in the next version. To come out this week I hope)

Code:

-- DCS LUA SCRIPT FOR THE FLYPT HEXAPOD INTERFACE
-- Copy this file to the folder %USER%/Saved Games/DCS/Scripts/Export.lua
-- If the Scripts folder doesn't exist, create it.

function LuaExportStart()
    package.path = package.path..";.\\LuaSocket\\?.lua"
    package.cpath = package.cpath..";.\\LuaSocket\\?.dll"
    socket = require("socket")
    host = host or "127.0.0.1"
    port = port or 4123
    c = socket.udp()
    c:settimeout(0)
    c:setpeername(host, port)
end

function LuaExportAfterNextFrame()
    local acceleration = LoGetAccelerationUnits() -- In g's
    local pitch, roll, yaw = LoGetADIPitchBankYaw() -- In radians
    -- Yaw output from 0 to 2*PI
    -- Roll and Pitch from -PI to PI
    --LoGetTrueAirSpeed() -- In m/s
    --LoGetModelTime() -- In s
    if c then
        -- The FlyPT Interface uses Z for vertical and Y to the front
        -- That's the opposite in DCS
        -- Besides that, vertical acceleration includes gravity, so we subtract 1 from the value (gravity is already present just by you sitting in the rig)
        socket.try(c:send(string.format("%.4f %.4f %.4f %.4f %.4f %.4f %.4f %.4f", acceleration.x, acceleration.z, acceleration.y - 1, yaw, roll, pitch, LoGetTrueAirSpeed(), LoGetModelTime())))
    end
end

function LuaExportStop()
    if c then
        c:close()
    end
end

Took some time to understand the values Well, not all this time.
Just posting the script here for my or anyone reference.
SimTools plugin is not working for me. I receive data with the script it's using, but for some reason I don't get anything in SimTools.

Next, maybe X-Plane and Race Room

iRacing would be a great addition too

I don't have and never had iRacing.
If you have a link or some info how they send telemetry, I could try. And testing is up to you

If that doesn't work out I bet those that use iRacing would be willing to get together and gift you a subscription . I don't like their business model myself so when I need some Nascar I just play good ole Nascar Racing 2003 Season which is what iRacing was built on.

Xplane would be fantastic.

The issue there is that we need a butter smooth heave while flying and raw rumble effect while on ground.

I found a good solution for that in my experimental sim tools plugin.

If you want help how to “bite” it I am available
